The first thing we must do for this case is to define variables.
We have then:
x = Tim's age
Now we write the equation:
x + 7 = 3 (x-19)
Answer:
Tim's age in 7 years will be three times what it was 19 years ago:
x + 7 = 3 (x-19)

A fast food restaurant sells between 164 and 328 hamburgers per day. If the company profits $82.00 per 82 hamburgers sold, appro

murzikaleks [220]

If the company earns $82 per 82 hamburgers then that means that the company earns $1 per burger sold. Therefore we are able to deduct that the company profits in between $59,860 and $119,720 a year. We know this because the minimum number (164) x 365 is 59,860 and the maximum number (328) is 119,720.

Generalize the pattern by finding the nth term. 6, 10, 14, 18, 22, ... options: A. 4n B. 4n + 2 C. 4n + 10 D. 6n + 4

elixir [45]

ANSWER

B.

$4n + 2$

EXPLANATION

The given pattern is:

6, 10, 14, 18, 22, ...

The first term if the pattern is a=6.

The common difference among the terms is

$d = 10 - 6 = 4$

The general pattern can be found using the formula:

$f(n)=a+d(n-1)$

We substitute the values to get,

$f(n)=6+4(n-1)$

Expand to get;

$f(n)=6+4n-4$

$f(n) = 4n + 2$

The correct answer is B.

Find the inverse of the function f(x) = 2x² - 3x NO ABSURD ANSWERS IF YOU DON't WANT YOURSELVES TO GET REPORTED!

Mila [183]

Answer:

$\boxed{f^{-1}(x)= \frac{\sqrt{8x+9}+3}{4}}$

Step-by-step explanation:

$f(x)=2x^2-3x$

$f(x)=y$

$y=2x^2-3x$

Switch variables.

$x=2y^2-3y$

Solve for y.

Multiply both sides by 8.

$8x=16y^2-24y$

Add 9 on both sides.

$8x+9=16y^2-24y+9$

Take the square root on both sides.

$\sqrt{8x+9} =\sqrt{16y^2-24y+9}$

Add 3 on both sides.

$\sqrt{8x+9}+3 =\sqrt{16y^2-24y+9}+3$

Divide both sides by 4.

$\frac{\sqrt{8x+9}+3}{4}= \frac{\sqrt{16y^2-24y+9}+3}{4}$

Simplify.

$\frac{\sqrt{8x+9}+3}{4}= \frac{4y-3+3}{4}$

$\frac{\sqrt{8x+9}+3}{4}= \frac{4y}{4}$

$\frac{\sqrt{8x+9}+3}{4}=y$

Inverse y = $f^{-1}(x)$

$f^{-1}(x)= \frac{\sqrt{8x+9}+3}{4}$
